CAR-TRUCK FOR ELEVATED RAILWNAYS.

SPECIFICATION forming part of Letters Patent No. 232,208, datedSeptember 14, 1880.

Application filed April 20, 1880. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WiLLsHIRE RILEY, a citizen of the UnitedStates, residing in Brooklyn, in the county ot' Kings and State of NewYork, have invented certain new and useful Improvements in Trucks forOenter-Rail ElevatedfRailroad Cars, of which the following is aspecification.

Heretofore, as shown in a patent issued to 1o me in the year 1876, No.173,240, the car has been retained on the track by two or moreguide-wheels bearing against the sides of a lower rail or stri 11g-piecewhose upper surface is broad and iiat, extending overthe sides, so

15 as to form a flange for the guide-wheels to hold against and preventthe ear from lifting or jumping the track.

rlhe object of my present invention is to afford increased safety andcomfort by the zo use of two or more fiatfaced wheels in combinationwith the truck, and utilize the top of the flange as well as its bottom,thereby affording a perfect and well-balanced gripe between the truckand structure, which will prevent the car from swaying, as well asspreading the strain more generally, by placing a portion of the weightof the car upon the safety-rails, which are situated below the maincentral rail at the base, the frame forming its support* 3o rail.

Figure 1 represents a side view. Fig. 2 is an end view of the same.

Similar letters of reference indicate corresponding parts.

In the case here presented the ear is provided with two double-flangedwheels, A, one being set at each end thereof, and in order to balancethe car perfectly upon the single rail B, I have two vertical wheels, CO, and two 4o horizontal wheels, D D, arranged on a single casting, E E,each side of the central wheels. These castings are rigidly attachedtothe ycastin g.

bottom of the car, so as to bring the wheelcenters all iu line, as shownin Fig. 1, and are stiffened in position by braces F F.

The horizontal wheels D have fiat faces, and are held in position by theshaft G, which extends upward through the lugs H II of the The saidwheels extend below the flange of the safetyrails I, and are of suf- 5ocient diameter to reach the exterior side. of the same.

The vertical wheels O C have dat faces and are journaled in ordinaryboxes, J, set in the casting. These wheels are designed to bear 55 ontop of the Iianges of the safety-rails di- -rectl y over the horizontalwheels, as shown in the drawings, so as to relieve any tendency of thecar to sway, and serve as a means of distributing the strain causedthereby upon the 6o whole structure.

I am aware that trucks for elevated railways have been made with asingle broadfaced bearing-wheel resting upon the tread of a T-track,with horizont-al driving-wheels bear- 6 5 ing directly against the sidesof the said track, and vertical wheels bearing upward against the underside of the saine, so as to house the said track by t-he truck-wheels.This I do not claim, but 7o What I do claim as new, andv desire tosecure by Letters Patent, is

A truck for center-rail elevated railroads, having centraldouble-flanged wheels A A, poised and held upon said rail by vertical 75 wheels O O and horizontal wheels D D, said wheels bearing upon andagainst flanged safety-rails situated below the center rail at each sideof the base of its support, substantially as shown and described.
